{"product_id":"cfprhtptfetc","title":"H-Type PTFE Test Cell (25mL+25mL) with Single\/Double Quartz Window for Fundamental Photoelectrochemistry (PEC) Research, CFPRHTPTFETC","description":"\u003cp\u003eAn H-type PTFE Testing Cell with a Quartz Window is the pinnacle of reactor design for researchers working in harsh electrochemical environments. While glass H-cells are common, the PTFE (Teflon) body is explicitly required when working with highly alkaline solutions (like 6M KOH for Zinc-Air or water splitting) or aggressive organic solvents that would otherwise leach impurities from, or etch, a glass surface.\u003c\/p\u003e\n\u003cp\u003eThe H-type geometry provides physical separation between the anode and cathode, while the PTFE construction ensures that the cell itself remains a passive participant in the reaction. (1) \u003cstrong\u003eChemical Superiority\u003c\/strong\u003e: PTFE is nearly universally inert. This is critical for N2 reduction (NRR) or CO2 reduction (CO2RR) research, where trace silicates or metal ions leached from glass can lead to \"false positive\" catalytic activity. (2) \u003cstrong\u003eQuartz Window (JGS1\/JGS2)\u003c\/strong\u003e: To allow light in, a flat quartz disk is compression-sealed into the side of the PTFE chamber. This provides \u0026gt;90% transmission for UV-Vis light, allowing you to illuminate your photoelectrode (FTO\/ITO) without the \"lensing effect\" caused by curved cell walls. (3) \u003cstrong\u003eDurability\u003c\/strong\u003e: Unlike quartz square cells, a machined PTFE block is virtually indestructible and can withstand accidental drops or high-torque clamping of membranes.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eCFPRHTPTFETC (C-FPR-HTPTFETC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eThe whole PEC test cell is made of PTFE, which is highly resistant to harsh electrochemical environments. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe side-illumination window is made of quartz with light transparence \u0026gt;95%.
